Choose capsules from them, and then take out the seeds inside, but you can't sow them directly. You have to disinfect first, so as not to worry. After that, the seeds are placed in a warm environment to ensure a suitable growth environment, and then slowly germinate into seedlings, and can be planted and cultivated after the growth state is stable.

Second, cutting.

Cut off the stem nodes from the plants in good growth condition and divide them into several individual plants. The length does not need to be too long, and it is best to ensure that there are growing points on it. Then prepare the substrate, insert the stem nodes into it to ensure a suitable growth environment, wait for the plants to take root and grow, and then transplant.

Thirdly, ramet propagation.

Usually in early spring or autumn equinox. First, select qualified plants with more top stems for more than one year. Dig them out of the loam, then cut off the excess withered branches and leaves, divide them into several plants from the bottom and replant them in the loam respectively.

Fourth, tissue culture.

This method is difficult to realize in ordinary families. Take a piece of root and stem from the plant, then put it in a tissue culture dish for a period of time, and then transfer it to a test tube for culture.
